So what about the slip yoke on the back of a Tracker transfer case? Is it the same, allowing you to run a doubler with the Samurai case behind the Tracker trans/t-case? It'd probably only work in a 4door because of wheelbase issues
No. The output shaft of a trackick tcase is a different size than the output shaft of a trackick transmission.
26 spline output shaftsAll 89-96 trackick tcases.
22 spline output shaftsAll 2wd/4wd trackick transmissions (89-98).
All samurai transmissions (86-95).
All samurai and trackick driveshafts use the same sized ujoints. So you could take the trackick 4wd slip yoke and put on a samurai intermediate shaft and the shaft would then slip onto an 89-95 trackick tcase output shaft.
Or you could just eliminate the whole "shaft" part of the samurai intermediate shaft and couple the slip yoke and the intermediate shaft end that bolts to the tcase flange together via the ujoint. But I believe that would make the shaft too short and the samurai tcase would actually have to be moved forward.
